VENTI LATl NGI-FAN Specieation of Letters Patent.

Patented Dee. 4, 1906.

Application led March 1, 1904. Serial No. 196.081

pipe provided with a reversing device whereby the water or other driving agent can be fed to either bucket-ring for eifecting rotation of the ventilator in the desired direction for suction or for blowing action, re-

. spectively.

to be hereinafter referred to.

1 is an outer casing, to which is secured an inner casing 2, divided into two chambers 4 5 by a partition 3. In the chamber 4 is located the ring-lubricator vbearing 6, while the chamber 5 contains the turbine 7. The casing 2 receives the shaft 8, running in the bearing 6, and on one end of the shaft is mounted the fan 9 and at the other end the turbine 7, designed as partial double turbine for working rby impulse from without and having a diskLLlO, on either side of which is a ring of scoop-buckets arranged to correspond with the direction of rotation. In the casing 2 above the turbine 7 there is located a rotary vertical reversing-pipe 1l, the axis of rotation of which lies in a plane passing through the center of the shaft 8, while its top end is furnished with a union stufIing-box 12, having a gland 13. The bottom end of the pipe 11 is provided with a nozzle 14, running eccentrically to the axis of rotation ofthe pipe.

15 is a groove running half round the pipe 11, and in this groove there engages a screw 16*, projecting through the wall of the casing 2, whereby the maximum angle of rotation of the pipe is limited to one hundred and eighty degrees.

17 is a lever whereby the pipe can be rotated.

The ventilator is driven by pressure-water fed to the turbine in a fine jet through the pipe 11 and nozzle 14, whereby turbine 7 and fan 9 are set in rapid rotation. The water iiowing off runs throuo'h the pipe 16. In order to prevent water from being thrown out of the chamber 5 into the chamber 4, which contains the bearing 6 and its lubricating-oil, the turbine 7 is provided with a dished rim 18, inclosed by rims 19 20, which together form a groove of dovetail section, within which the rim 18 can rotate without obstruction. Should water be thrown between the turbine and the rim 19, it will impinge against the rim 18, and then in consequence of the high speed of rotation of the turbine will, owing to the centrifugal action, be thrown toward the oints of highest circumferential velocity. rom there it will be thrown off and caught by the annular rim 19, down the inner walls of which the water will run, finally flowing back into the chamber 5 through the aperture 21, located at the lowest part of the annular rim 19. If, ho'wever, any Water should be thrown round the rim 18, it will impinge against the annular rim 20 and will collect at the lowest point of the latter, from there dropping onto the inclined inner surfaceof the rim 18. From here the water will be thrown to the points of highest circumferential velocity, and iiying from there will be caught up by the rim 19. It will then rundown the walls of the latter and will finally flow off through the aperture 21 into the chamber 5, as before. Thus the water is absolutely prevented from getting access to the oilchamber 4. The purpose here in View is to provide a thorough joint between the chambers 4 and 5 without there being any friction or consumption of power.

To reverse the turbine, the lever 17 must be turned through an angle of one hundred and eighty degrees, wherebyl the pipe 11 is likewise caused to turn through the same angle. Owing to the eccentric position of the nozzle 14, the above rotation will cause it to be transferred from one bucket-ring to the other ring with reversed buckets. In this manner the turbine can be rotated in the opposite direction by the jet from the nozzle 14 and the fan 9 caused to suck over air from, for instance, the side C instead of forcing it over to such side.

Air sucked into a confined space from without is usually dry and dusty. For the purpose of rendering s uch air humid and for IOO IIO

removing the dust the following method is adopted: Concentric with the shaft 8 and surrounding the casing 2 a cylindrical mantle 22 is provided, projecting beyond the casing 2. The mantle 22 is secured at one end to the casing l and at the other end is p-rovided inwardly with a gutter 3l. On the left-hand side of the casing 2 a nozzle 23 is provided, lying concentrically to the mantle `22 and'directed toward the `gutter end of the same. Pressure-water is supplied to ythe 'nozzle 23`by means of a lpipe 24. In vfront of the `nozzle 23 is an atomizer 25, which by -means of a deflector-surface diffuses the spray of water issuing from the nozzle. The de- .iector-surface is provided with grooves, as shown vinFig. 3. These grooves run'concentrically round the prolonged aXis of the nozzle and present deflecting-surfaces lying inclined 'to and turned laterally lfrom the prolonged nozzle-axis, so that the water-jet im- 'pinging against them rebounds in nely-divided condition. The current of air passing through :the mantle 22 ytakes up a portion'of the diffused spray of water, and ithus lenters the room or the 'like in .suitably humid condition. 'Those particles of water which pass the air-current but are not taken zup -by it extract the particles of dust contained inthe .air and are caught up by the mantle-walls,

along which they run into the gutterSl. 26 is the eXit from the gutter, through which the said water 'runs into a collector, escaping iinally through the outlet 27 of the same.

Owing to the water being thrown vbackwardby the adeflector-surfaces, the air is enabled to mingle Vquickly and intimately with it, and the particles which are not taken up by `the air-current are more readily caught vby the mantle 22, the length of which can thus be relatively short. During Vthis moistening and purifying process the air can also be' cooled., as the Aquantity of heat necessary for vaporization of the ,spray of water is taken from the air blown through, which is therefore cooled.

'In order to prevent thefree access of air Vto the room being ventilated, when the ventilator is not working, flaps 28 are provided. These flaps are hinged to the casing v1 and can be closed by drawing the cord 29, while on release of the latter they open automatically under the influence of a spring 30.

The bearing 6 is lubricated by means of a spiral spring 32, coiled on the shaft 8. The lower portion of the spring dips into the oil, and owing to the friction between rotating shaft and spring the latter is slowly rotated and lifts oilonto the shaft.

The employment of a spiral lubricatingspring enables the lubricating member to be vapplied to the shaft at any lmornentfwhereas with a closed ring vbearing :as ordinary this can only be done with split rings.

By the provision of scooped buckets the Water-power can be better utilized than is the case with straight radial blades or corrugated sheet surfaces.

Having now particularly described and ascertained the nature of the said invention, and in what manner the same is to be performed, I declare that what I claim isl. In a Ventilating apparatus 4the combination with a fan and apturbinehaving a lateral `projecting ring; of a shaft common to both of them, an inner casing, anfoil-reservoir and voir also having a lateral projection surrounding-one of the bearings projecting 'towardthe turbine and within the laterally-projecting ring thereon.

2. I n a Ventilating apparatus the combina- 'tion vwith a fan and a turbine having a laterally-projecting ring; of a shaft common yto both of them, an inner casing, `an oil-reservoir and bearings on the inner casing, a 'partition separating the turbine and reservoir and having a pair of projecting ilanges concentric with 4the shaft thereby forming a substantially dovetailed groove between them and into which the ringon the turbine projects, substantially as described.

In testimony whereof I have signed lmy name to this specification in the presence of two subscribing witnesses.
